241 heads ported by Pavlock.
Spoke to him and said they should flow 310-320 @600 lift. Also said was no difference in the ported 241's and ported 243's except for the combustion chamber which does not make enough difference to notice on the street.

First off the Stage I ported head is a budget port job. They do not flow 310-320 CFM at .600 lift that is impossible with a 2.00 inch valve and a street friendly valve job. I do the cylinder head work at Pavlock's so whoever gave you the numbers are wrong. Flow numbers for stage I heads are
.100 67cfm
.200 135cfm
.300 197cfm
.400 241cfm
.500 270cfm
.600 284cfm
.650 285cfm
Thats with a Competition valve job cut. If you didnt get the valve job too then the numbers will be slightly lower. Now compared to a LS6 head in stock form here are the flow numbers
.100 62
.200 130
.300 184
.400 228
.500 251
.600 256
.650 257
The stage I heads will make more power than a stock LS6 head but are by no means a race head. The head offers a great power increase for the guys looking to get a set of heads for less than 1k. The flow numbers you are stating above are what our Stage II options are flowing. They also have slightly larger valves and much more extensive port work. The stage II options carry close to a 2k price tag
